This invention relates to driving mechanisms for washing machines and concerns it self primarily with an 'zation l'iaving a novel form of clutching mechanism for con necting the driving member with the driven member.

The invention comprises the novel mocha nism and combinations hereinafter described and more particularly pointed out and defined in the appended claims.

In the accompanying drawings which illustrate a preferred ombodin'icnt of this vention and in which similar reference numerals refer to similar features in the different views:

Figure 2 is a fragmentary sectional view taken substantially upon the line 2--2 of Figure 1 with parts in elevation.

Figure 7 is a sectional view upon the line 7-7 of Figure 3 with parts in elevation.

As shown in the drawings: There is shown in dotted lines, a rotary washing machine cylinder 1 which is oscillated backwards and forwards by the driving mechanism which is connected to the central spindle support of the cylinder.

This driving mechanism consists of a motor 2 which is supported beneath the cylinder. The motor shaft 3 is geared in any ap propriate way (not shown )to a shaft suitably ournalled in the frame of the washing machine. An eccentric 5 is secured upon the shaft 4: and the eccentric strap that sur rounds the eccentric is provided with an arm 6 which extends upwardly and is pivot ed to an oscillating lever 7 which is loosely journalled upon a shaft 8 supported at one end in a stationary transverse frame member 9 of the washing machine. The shaft 8 is provided with a collar 10 that bears against the bearing niiembcr 9 and beyond the collar 10, a hollow cylindrical clutch member 11 is rotatably mounted upon said Serial l lo. 655,165.

shaft 8. The end of the clutch member 11v extends beyond the end of the shaft 8 and is "o ovided with polygonal aperture 12 co .i with said shaft for receiving the aforementioned spindle of the washing machine cy noer. The hollow clutch member 11 is pl'OVlufid with an opening 13 (Figure 41) three '11 \VllECl'l the lever freely extends; the

. ow clutch member 11 is further 'xvidcd with a longitudinally extending slot 15 upon the center line of the slot and the lover 7 is likewise provided with a slot or r ortise upon its inner side as indicated at 16 in Figure 6. A clutch key or member as 1.7 is positioned so to slide in the slot 15 and its end is so fashioned to readily enter the slot or mortise 16 in the lever 7.

The clutch key 117 has a right angled extension or tail 18 that extends through an arcuate and vertically extending guide slot 19 in a hamn'ier ring 20 that surrounds a portion of the clutch sleeve 11 and forms a bearing therefor. A pin 17 extends througl'i the end of the extension and retains the clutch key in position. The hammer ring 20 is integral with a rod 21 that is slidingly mounted in the frame member 9 and its outer end slides through a recess in an end supporting block 22. A pin 23 extends through the rod 21 and a coil spring 24 is confined between the block 22 and the pin 23 which normally tends to project the rod 21 toward clutching position.

The rod 21 is normally held in clutching position by the spring with the clutch toy 1? in operative engagement with the lever 7. But the rod 21 may, however, be retracted from such position by a slidino, actuator 25 which is suitably supported adjacent the beam 9 and is provided at its remote end with a wedge shaped formation that engage the pin 23 and slides the rod 21 into inoperative position when the actuator is properly operated. For operating the actuatmf, a lever 26 is pivoted intermediate its ends to a block 27 upon the beam 9, the

lower end of said lever being pivoted in a bifurcation formed 1n the end of the act uator.

The operation is as follows: In the op.- eration of the washing machine by the aforementioned driving mechanism, the m0- tor will rotate the eccentric which will 0scillate the lever 7 ti rough the eccentric arm 6. New, assuming that the actuator 25 has been retracted so that the spring 24 will have shitted the clutch key 17 into the slot or mortise 16 in the lever 7 it is evident that the clutch cylinder 11 will partake of the oscillations of the lever 7 and oscillate the washing cylinder which is connected to the clutch cylinder 11, the clutch key 17 forming the connection between the lever 7 and clutch cylinder 11. When it is desired to declutch the driving mechanism from the cylinder, the actuator 25 is shifted to retract the rod 21 and hammer ring 20 whereby the clutch key 17 is retracted from its engagement with the lever 7.

I am aware that many changes may be made, and numerous details of construction may be varied through a Wide range Without departing from the, principles of this invention, and I therefore do not purpose limiting the patent granted hereon, otherwise than necessitated by the prior art.

I claim:

1. In a washing machine drive, a stationary support, a cylindrical member rotatable upon said support and adapted for clutching relation with a member to be driven, an oscillating member upon said support, means connecting said oscillating member and cylindrical member for conjoint oscillation, and means for actuating said first means to disconnect said cylindrical member from operative connection with said oscillating member, said first means comprise lation, and means for actuating said first.

means to disconnect said cylindrical memberfrom operative connection with said oscillat member, said. .second means comprisins, a spring impelled member rigidly secured to said first means and a wedge shaped lever adapted to retract said spring impelled member.

In a washing machine drive, a stationsuppert, a cylindrical member rotatable j on said support and adapted for clutchig reiation with a member to be driven, an oscillating member upon said support, means connecting said oscillating member and cylindrical member for conjoint oscillation, and means for actuating said first means to disconnect said cylindrical member from operative connection with said oscilla... member,said first means comprising a ring surrounding said; support, a key n'iember adapted to be actuated into engag position by said ring but adapted to osci with respect thereto, said second means comprising a spring impelled member rigidly secured to said ring and a wedge shaped lever adapted to retract said spring impelled member.

In testimony whereof I have hereunto subscribed my name.
